During the last decades, transurethral resection of prostate remained the gold standard for treatment of Benign Prostatic Hyperplasia. Among the numbers of new types of diagnostic and treatment methods, we should follow closely the recommendations made by guideline of EAU for benign prostatic hyperplasia. Sonography, urodynamic evaluation and appreciation of residual post voiding urine can be considered as one of important methods of diagnostic. Ultrasonography will determine the prostatic volume, size of adenoma and will exclude or diagnose other possible bladder or prostate pathology. Conservative treatment of BPH is the first step for most patients with lower urinary tract symptoms (LUTS) bearers of the benign prostatic hyperplasia (BPH) but some patients may have exact treatment goal. Efficiency of TURP remain unexcelled last decades with substantial increasing of positive symptoms after resection (IPSS, Q-max and PVR). The reoperation rate after TURP is around 10% in 5-7 years but treatment of appeared complications is necessary to perform bit earlier during 1 -2 years after resection. Although transurethral resection of prostate is associated with a rate of intraoperative, postoperative early and long-term complications it is considered to be reference standard for minimally invasive surgical treatment of lower urinary tract symptoms (LUTS) due to benign prostatic obstruction (BPO).
